IFRS 16 (international) and ASC 842 (US GAAP) were designed in parallel and share the same core principle: leases go on the balance sheet. But the two standards diverge in several important ways — some minor, some significant enough to change how you structure leases and present results.
Here’s a practical side-by-side breakdown.
The Big Picture: What’s the Same
Before the differences, what’s aligned:
- Both require a right-of-use (ROU) asset and lease liability for most leases at commencement
- Both use present value of future payments discounted at the appropriate rate
- Both have a short-term exemption (≤12 months)
- Both apply to lessees — lessor accounting differs more significantly but is less commonly impacted
- Both require disclosure of maturity analysis, weighted-average rates, and future lease obligations
Difference 1: Lease Classification
This is the biggest practical difference.
ASC 842 (US GAAP)
Leases are classified as either operating or finance based on five classification tests:
- Transfer of ownership by end of lease
- Purchase option the lessee is reasonably certain to exercise
- Lease term is for the major part of the asset’s remaining economic life (typically ≥75%)
- Present value of payments is substantially all of the asset’s fair value (typically ≥90%)
- Asset is specialized with no alternative use to the lessor
If any criterion is met → finance lease. Otherwise → operating lease.
IFRS 16
IFRS 16 does not distinguish between operating and finance leases for lessees. All leases (above the thresholds) are treated like finance leases: depreciation + interest, front-loaded expense, financing cash flow for principal.
Why it matters
Under US GAAP, a company with mostly operating leases reports a single flat lease expense line — straightforward, non-volatile. Under IFRS 16, that same company reports depreciation + interest — EBITDA goes up, but profit is front-loaded in early lease years.
Difference 2: Discount Rate
ASC 842
Use the rate implicit in the lease if readily determinable. If not (usually the case), use the incremental borrowing rate (IBR). Private companies have a practical expedient to use the risk-free rate instead of the IBR.
IFRS 16
Same hierarchy: implicit rate first, then IBR. No risk-free rate option for private companies.
Difference 3: Short-Term and Low-Value Exemptions
ASC 842
One exemption: short-term leases (term of 12 months or less at commencement). Election is made by class of underlying asset. No low-value exemption.
IFRS 16
Two exemptions:
- Short-term leases — same as ASC 842, ≤12 months
- Low-value asset leases — assets with a value when new of approximately $5,000 USD or less. Election is lease-by-lease.
Difference 4: Income Statement Presentation
ASC 842
| Lease type | P&L presentation |
|---|---|
| Operating | Single lease expense line, straight-line |
| Finance | Depreciation (straight-line) + Interest expense (effective interest) |
IFRS 16
Since all leases are treated as finance leases: Depreciation of the ROU asset + Interest expense on the lease liability. Total expense is front-loaded for every lease.
Difference 5: Cash Flow Classification
ASC 842
| Payment type | Cash flow classification |
|---|---|
| Operating lease payments | Operating activities |
| Finance lease — principal | Financing activities |
| Finance lease — interest | Operating activities (or financing if policy election) |
IFRS 16
| Payment type | Cash flow classification |
|---|---|
| Lease liability — principal | Financing activities |
| Lease liability — interest | Operating or financing (policy choice) |
| Short-term / low-value | Operating activities |
Side-by-Side Summary
| ASC 842 (US GAAP) | IFRS 16 | |
|---|---|---|
| Lessee classification | Operating or Finance | Single model (all “finance-like”) |
| Short-term exemption | ≤12 months, by asset class | ≤12 months, by asset class |
| Low-value exemption | None | ~$5,000 USD, lease-by-lease |
| Discount rate | IBR (or risk-free for private) | IBR |
| Operating lease P&L | Single flat expense | N/A — all depreciation + interest |
| Finance lease P&L | Depreciation + interest | Depreciation + interest |
| Operating lease cash flow | Operating activities | Financing (principal) |
| Effective date | 2019 (public), 2022 (private) | 2019 |
Frequently Asked Questions
What is the main difference between IFRS 16 and ASC 842? Classification. ASC 842 keeps the operating-versus-finance lease distinction for lessees; IFRS 16 uses a single model where lessees treat almost all leases like finance leases — depreciation plus interest, with front-loaded expense.
Does IFRS 16 have operating leases? Not for lessees. IFRS 16 eliminated the operating/finance distinction on the lessee side — every in-scope lease is recognized with an ROU asset and lease liability and expensed as depreciation plus interest. Lessor accounting still distinguishes the two.
Does IFRS 16 have a low-value lease exemption? Yes. IFRS 16 exempts leases of low-value assets (roughly $5,000 or less when new), elected lease-by-lease, in addition to the short-term (12 months or less) exemption. ASC 842 has only the short-term exemption.
Can one Excel workbook handle both ASC 842 and IFRS 16? Largely yes. The underlying math — present value of payments, amortization waterfall, ROU rollforward — is identical. The difference is presentation: under IFRS 16 you treat every lease like a finance lease and skip the operating-lease split.
Building the Schedule
Whether you’re under ASC 842, IFRS 16, or both, the underlying math — PV of payments, amortization waterfall, ROU asset rollforward — is the same. The difference is in presentation and classification.
If you need the period-by-period entries, see ASC 842 Journal Entries: A Complete Guide with Examples — the operating-lease split applies only under US GAAP; under IFRS 16, treat every lease like a finance lease and skip the operating-lease section.
The ASC 842 Lease Accounting Workbook is structured around US GAAP but the amortization math and journal entry logic is compatible with IFRS 16 as well.
